The TO1 is a carbon wrapped cartridge for
the industry's best-selling Whole House water filter, Model U25.
The TO1 also fits OMNI Whole House filters OB1 and OB5 as well as the older models, R12, R14 and Omni Regular Whole House water filters.
By reducing sediment and chlorine in incoming water, the
TO1 provides clean water to every faucet and appliance in your house. This cartridge replaces the
TO1 SS and DS.

If you have an
older Omni filter model that has been discontinued and need O-Rings or
cartridges,
please call our customer service number: (855) 855-1976 for assistance.

Because of the product’s limited service life and to
prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced
every ten years. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately.
Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
